OF NEW YORK, N. Y.

GASKET FOR JARS.

SPECIFICATION farming part of Lette Application filed Octob. r 10, 1885.

To all whom, it may concern:

Be it known that I, EDWIN R. DEVERILL, a citizen of the United States of America, and a resident of the city of New York, State of New York, have invented a new and useful Improvement in Gaskets for Metal Screws on Oans or Jars Containing Liquids or Semi-Liquids, of which the followingr is a specification.

I out two blanks, A and B, of any shape and thickness desired-one, A, from ordinary cork, and the other, B, from linoleum. I then join these two blanks together, either by riveting or bolting` them to the solid end of a male screw, as in Figure l of the drawings; or they may be placed loosely in a recess formed at the base of a female screw, as in Fig. 2 of the drawings; or they may be placed loosely on the flange at the base ofa male screw, asin Fig. 3 of the drawings, but aiways in such a position that the linoleum may come in contact with the valveseat, and that the cork may be protected from the wearing effect of the valve-seat striking it. By this combination I gain the flexibility of the cork (which is very desirable for a nice adjustment of the valve-seat) and the imperviousness and durability of the linoleum, and I avoid the porousness of the cork and the rigidity of the linoleum, which makes it of itself a poor gasket.

As I can use the commonest cork for my purpose, I am enabled to produce a cheaper and more perfect gasket than the cork alone, which is now the prevailing custom.

My invention is designed more especially for metal screws used on all kinds of oil cans or vessels; but I do not confine myself wholly to these.

I claim as my invention- 1. The combination, with a vessel for containing liquids, ofagasketor washer composed of two sectionsone of cork and one of linoleum-so placed as to always bring thelinoleum in contact with the valveseat, as and for the purpose set forth.

2. A gasket for any vessel containing liquids, constructed of two sections-one of cork and one of linoleum-as described, and for the purpose set forth.

In testimony that I claim the foregoing as iny invention I have signed my name, in presence of two witnesses, this 16th day of September, 1885.
